DUMPI1\TG -BODY FOB. VEHICLES.

Specification of Letters Patent. Patented Sept. 14, 1920.

Application filed September 16, 1919. Serial No. 324,084.

To all whom it may concern:

Be it known that I, LEWIS B. NELsoN, a citizen of the United States, anda resident of W'allingford, in the county of Emmet, State of fowa, haveinvented certain new and useful Improvements in Dumping- Bodies forVehicles, of which the following is a specification.

The present invention relates to an improved construction of dumpingbodies for Vehicles, and has for its primary object to provide aconvenientand practical means for dropping and closing the swingingbottongl sections of the body in discharging a loa A further object isto so construct the operating means for dropping and closing the bottomsections, as to enable the load to be either discharged at one operationor gradually deposited over a wide area.

Further objects will appear upon reference to the accompanying drawing,in which- Figure 1 is a side elevation of a vehicle body, constructed inaccordance with the invention; V

Fig. 2 is a longitudinal section of a vehi cle body, constructedaccording to the invention;

Fig. 3 is a cross-section; and

Fig. 4 is another longitudinal section, showing the operating. means ina position for discharging part of the load.

Referring to the drawing in detail, the body of the vehicle is dividedlongitudinally into two compartments by the medial partition 5. Each ofthe compartments isconstructed with a swinging bottom 6, which is hingedto the side of the body, as at 7, and extends the entire length, andpracti cally the entire width, of the bottom of the compartment, inorderto permit an unobstructed discharge of the load. Curved metallicsheets 8 are arranged to prevent any of the material which is to bedischarged from crowding into the corners of the body. Both of theswinging bottom sections 6 are adapted to swing toward and away from themedial partition 5.

The operating means for the swinging bottom sections 6 comprise a pairof horizontal rocker arms 9, pivotally mounted on the medial partition 5by means of the links 10. Each swinging bottom section is connected tothe links 10 by means of the flexible connection 10. Each of the rockerarms 9 is provided with independent actuating means, such as thetogglejoints, consisting of the links 11, pivoted at one end to therocker arms, with their other ends pivoted to operating levers 12. Theoperating levers 12 are located adjacent the drivers seat, in convenientreach for the driver to manipulate them in discharging the load.

As stated, each of the swinging bottom sections 6, by means of the abovedescribed operating arrangement, is capable of being opened and closedindependent of the other; thus, either the entire load may be dischargedfrom both compartments at the same time, or one compartment dischargedwithout the other. Now, attention is called to the pawl and ratchetarrangement on the levers 12, which enables them to be thrown anydesired distance and maintained in any position. With this arrangement,it is possible to open the swinging sections 6 the desired width togradually deposit the load over a wide area.

Claims. c

1. In a dumping body for vehicles, a pair of bottom sections adapted toswing longitudinally of the medial line of the body, operating means forsaid sections, comprising a pair of horizontal rocker arms, eachconnected by flexible members to one of said sections, and levers foroperating each of said rocker arms, said levers connected to said rockerarms by a toggle joint.

2. In a dumping body for vehicles, a medial partition dividing the bodylongitudinally into two compartments, a swing.- ing bottom for. eachcompartment, and means for opening and closing each bottom sectionindependent of the other, comprising a pair of horizontal rocker armspivotally mounted on the medial partition and connected byfiexible'members to each bottom section, and operating levers for therocker arms.

3. In a dumping body for vehicles, a medial partition dividing the bodylongitudinally into two compartments, a swinging bottom for eachcompartment, and means for opening and closing each bottom sectionindependent of the other, comprisgle joints.
